The RC is not opposed to reviewing any rule, but deciding
instantaneously to throw out a long standing rule just because some
new instrument came along is not a good idea.

Some people are not suggesting that the rules should be changed, only
that an instrument that has a disabled AH should not be prohibited.

The objections to inspecting the log are surprising since I thought
that was to be the proposed method of enforcing FLARM use.

Rather than saying an instrument with a disabled AH is banned under
SSA contest rules, wouldn't it be more constructive to define what
method of disabling would be acceptable, and then for the manufacturer
to consider implementing that provision?

What is the rules committee position on flying with a Garmin 396 or
496, or even LK8000. *All of these provide a crude AH that may or may
not assist in maintaining control in instrument conditions.

As to those that think having an AH will save you I hope you have some
instrument training, or better an instrument rating. *Flying in IMC on
instruments, particularly recovering from an upset, is not as easy as
some might think.

What you describe is exactly what the RC is working on.
A related issue is how to reliably disable non approved functions
without having the scorer be required to monitor
this.
We have had constructive discussions with the Flarm folks about how to
do this outside the flight log and practical
solutions appear to be available. All of this related to Flarm is on
hold till we get some practical experience.
The RC determination on this topic will be forthcoming quite soon.

The Rules Committee has posted the policy on using instruments that
provide features enabling flight without reference to the horizon.
